Watch Canon EF 135mm f2.8 Softfocus Lens Autumn Photowalk

After struggling a bit with the 55-200mm lens at a previous photoshoot due to the smaller apertures on the telephoto end, I wanted something faster in the telephoto range. Given that the EF-M system doesn't have anything fast and telephoto, my other solid option was to get the EF to EOS M adapter and a EF or EF-S lens.
